2,777,516 Patented Jan. 15, 1957 in view as will moreffullyappear in thespecification, the

invention intendedto' be protected by Letters Patent consists of thefeatures of construction, the parts and combinations thereof, and themode of operation, as herein- .a'fter described or illustrated in theaccompanying drawings, or their equivalents.

Referring to the drawings, according-to the illustrative-embodiment ofthe invention, the strip feeding dc- -vice-is embodied in a'unitarymachine notconnected in any larger machine orsystem.

'As shown in Fig. 2, it comprises a bed plate llresting on -blocks"12'which are in turn mounted on stanchions or legs 13.

:andatLtheir tops :to :the legs 13. The rear of the machine (seenalsoFigs. -4.and 9) is reinforced by cross bracest'lfl connected at theirupper ends to the blocks '12 sand; atltheir lower. ends torearanglepiece 14. Spanning -With the -above primary and otherincidentaleobiects 1 another gear '24 on shaft 21.

.The machine acts upon-a continuous web of. paper materialZS (Figs. 1andS) drawnfromsa pack 26 supportedby away- 27 on the frontofthemachine. From the tray -'27 a paper. guide 28 (Fig..8) extendsaupwardly and rearwardly,.terminating at a support .29 mounted on thezbed.plate 11. The top surface of the support '29 lies in aplanesubstantiallycoincidentwith the'upper edgeofadie 31, which asshownin Fig. 5, is made up 'Ofseparatefmnt, rearand end'elements so thatindi- .vidualcomponents-thereofmay be replaced when necessary because oflocalized wear or in order to change the shape of the die. A shoe plate32 rests on the bed plate :11 andprovidesamountingfor. the die 31whichhas a central opening 33. The side-walls of the opening 33 areslightly undercut while-around the rim of such openingthe=die31 isformed with an upturned .flange34. Openings 35 and 36 in the-shoeplate32 and bed plate 11, respectively, lie beneath the die. opening -33 andprovide forncommunicationtherewith of. a chute 37. As shown in Fig.:2tthechute v137' extends. downwardlyiand forwardly inzthemachine,terminating in a tray '3 (Fig. '1) at th frontzthereof.

The die opening 33 is shaped to conform to the outline of a businessmachine card and receives a correspondingly shaped punch 39 in opposedoverlying relation to the die 31. The punch 39 is rigidly connected bybolts 41 (Fig. 8) to a punch holder 42, the punch being in etfcct a partof the holder 42 which i in spaced parallel relation to the shoe plate32 and the bed plate 11.

The holder 42 has attached thereto four corner posts 43 which extenddownwardly through bushings 44 installed in registering openings in theplates 32 and 11. The inner or lower ends of the posts are eachpivotally connected to a respective lever 45. Each lever 45, as shown inFig. 6, is pivotally mounted at its mid point on a stud 46, the leversbeing arranged in opposed pairs adjacent to each. side of the machine.On each side of the machine is a side plate 47 each mounting a pair ofthe studs 46. Each pair of levers 45 is pivotally connected at the outerends thereof to respective posts 43 and at its inner ends to a commonpin 48 carried by an arm 49. Each arm 49 has an opening in which ismounted an eccentric 51 fast on the shaft 21. Rotation of the shaft 21,therefore, serves to oscillate the levers 45 which in turn imparts areciprocating motion to the posts 43 and to the holder 42 and its punch39, carried thereby. The extremes of motion of the punch 39, under thismovement, are substantially as indicated in Figs. 7 and 8.

The web 25 has imprinted forms 52 thereon representing the cards to becut from the web. The forms are disposed longitudinally of the web, inspaced relation to one another. They are brought, in a manner to bedescribed, successively to register with die opening 33. Upon eachdescent of the punch 39, therefore, from the position of Fig. 7 to theposition of Fig. 8, a form or card 52 is cut from the web 25 and dropsdownward through openings 33 and 35-36 into chute 37.

In order to tilt the cards for endwise sliding motion down the chute 37,and in order to preclude inisoperation resulting from entanglement ofthe frame work of the web with the edge of the die, there is provided aplunger 53 (Fig. 7) slidably mounted in a bushing 54 in the bed plate11. The upper end of the plunger 53 has an inclined and transverselyelongated head 55 thereon (see Fig. and is received withinthe dieopening 33 adjacent the back end thereof. The lower end of the plungeris pivotally connected to one end of a lever 56 mounted intermediate itsends on a bracket 57 fixed to the underside of the bed plate 11. One endof the lever 56 is connected to the plunger 53. The other end thereofcarries a roller riding the periphery of a cam 58 secured to shaft 21. Acoil spring 59, interposed between the bushing 54 and a collar 61 on theplunger, urges the assembly of parts comprising plunger 53, and lever 56in a direction to maintain the roller on lever 56 in contact with cam58.

The construction and arrangement of cam 58, which rotates with the shaft21 and eccentrics 51, is such that the plunger 53 is Withdrawn throughthe major portion of each revolution of shaft 21, the head 55 duringthis interval occupying the position shown in Fig. 8. As so positionedit is out of the path of travel of the punch 39 but yet is in positionto tilt or deflect the cut card. As the punch 39 rises out of the dieopening 33, the plunger 53 is permitted to follow, attaining theposition of Fig. 7 wherein the head 55 thereon constrains the web 25 topass over the die 31 without interference with the edges thereof.

The web 25 has a continuous series of perforations 62 adjacent to eachside margin thereof and outside the borders of the cards 52. Cooperativewith each series of perforations 62 is a feed device 63 presentingradial pins 64, the devices 63 occupying spaced apart positions on ashaft 65 pivotally mounted in brackets 66 secured to the sides of apressure member 67. The member 67 is dependent from the punch holder 42,being supported by bolts 68 (see Figs. 4 and 8) for limited reciprocablemovement relatively thereto. Springs 69 are interposed between themember 67 and the holder 42 so as to yieldingly maintain the member 67in its outward position for motion with the holder 42.

in the descent of the punch holder 42, the pressure member 67 contactsthe raised flange 34 on die 31 at or at about the time punch 39 beginsto enter the opening 33. The web 25, which is stretched across the die31, is thereby positively arrested and held from movement during thecard cutting operation.

The pressure member 67 also provides a guide for the web in the form ofspaced apart plates 71 and 72 (see Figs. 5 and 8) which are fastened tothe underside of the member 67 at spaced points in front of and behindthe flange 34 on die 31. The upper surfaces of the plates 71 and 72, orthose facing the member 67 are recessed to accommodate the web 25 whichthereby is guided and supported by the plates 71 and 72.

Beyond the rear plate 72, the web 25 encounters the feeding devices 63,the pins 64 thereof engaging perforations 62 for positive advancement ofthe web in synchronism with rotation of the feeding devices. Pressurefingers 73 on the brackets 66 embrace the feeding pins 64 and hold theweb in engagement therewith. A guide member 74 (Fig. 8) deflects theuncut remnant of the web to the rear of the machine as it leaves thefeeding devices 63.

The shaft 65, on which the feeding devices 63 are mounted, is connectedthrough a universal joint 75 to a stub shaft 76 extending into a housing77 at one side of the machine. Also extending into housing 77, throughthe side plate 47, is the drive shaft 21 to the outer end of which isfixed a gear 78. A hearing 79 on the shaft 21, and a rib 81 integralwith side plate 47, support a mounting plate 82. The stub shaft 76 isjournaled in the mounting plate 82 and has secured thereto a gear 83,driven by the gear 78 through intermediate gears 84, 85, 86 and 87, allmounted in the plate 82.

As seen in Fig. 8, the toothed area of the gear 78 extends over only apart of its periphery. Accordingly, while rotation of the shaft 21 andgear 78 is continuous with operation of the motor 19, the transmissionof a driving force through the gear train 83-87, shaft 76, and joint 75to the shaft 65 is interrupted during a part of each revolution of theshaft 21. It will be understood that the construction and arrangement ofparts is such that ,the gear 78 loses meshing engagement with gear 87just prior to the moment the punch 39 enters die opening 33, and thatsuch meshing engagement is resumed just after the punch leaves dieopening 33. It will further be understood that the duration of meshingengagement of the gear 78 with the gear 87 is predetermined to produce atravel of the web 25 just sufficient to move the previously cut portionof the web out of registry with the die 31 and to bring the nextsucceeding imprinted form 52 into registry with the die.

In loading the machine, the feeding devices 63 may be rotated by hand,through a knob 88 on the shaft 76, to place the web in the desiredstarting position.

In further regard to loading of the machine, when the supply pack 26 isdepleted and the motor 19 stopped, the position of the punch 39 relativeto the die 31 may make it difiicult or impossible to insert the leadingend of a new web. Accordingly, means are provided for manually movingthe punch holder 42. Thus, a side cover 89 (Fig. 5) on the machine has areinforcing plate 91 secured thereto. Installed in the assemblycomprising the cover and plate is a bearing 92 mounting a stub shaft 93.An arm 94 is secured to the shaft 93, on the inside of cover 89, and haspivotally mounted thereon a pawl 95 (see also Fig. 2). One end of thepawl 95 is presented in cooperative relation with the gear 23 on the endof the drive shaft 22. The other end of the pawl engages a pin 96projecting laterally from the plate 91 through the cover 89, such otherend having an inclined surface 97 in contact with the pin 96. A spring98 urges the pawl 95 in a counterclockwise direction (Fig. 2) or in adirection to engage it with the gear 23. In the normal position of theparts, however, the pawl is held by the pin 96 in the disengagedposition of Fig. 2 so as not to interfere with operation of the gear 23by the motor 19. Should the arm 94 be moved downward, or in acounterclockwise direction, the pawl 95 is carried bodily therewith andat the same time is allowed to rock about its pivot on the arm 94 toengage the gear 23 (see Fig. 7). An oscillating motion of the arm 94thus will produce a step by step rotary movement of the gear 23 andparts driven thereby. The described oscillatory motion of the arm 94 iseffected by a hand crank 99 secured to the shaft 93 outside the cover89. The crank normally is held against movement by a resilient seat 101defined by a leaf spring 102 mounted on a plate 103 on the cover 89.

The operation of the machine will be largely selfevident from thepreceding discussion. The drive shaft 21 rotates continuously withoperation of the motor 19. In response thereto the punch holder 42-continuously reciprocates relatively to the die 31 and the feedingdevices 63 are intermittently actuated to bring successive cards 52 inthe web 25 to registry with the die 31. The presser member 67 iseffective to arrest and hold down the web during the cutting operation,while the plunger 53 deflects the cut card into the chute 37 andprevents entanglement of the web with the edges of the die.

From the above description it will be apparent that there is thusprovided a device of the character described possessing the particularfeatures of advantage before enumerated as desirable, but whichobviously is susceptible of modification in its form, proportions,detail construction and arrangement of parts without departing from theprinciple involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has beendescribed in language more or less specific as to structural features,it is to be understood that the invention is not limited to the specificfeatures shown, but that the means and construction herein disclosedcomprise but one of several modes of putting the invention into eifect.

Having thus described my invention, I claim: A strip feeding device,including guide means for con- 'tinuous web of paper material, said Webcontaining imprinted forms, die and punch elements in opposed relation,said die presenting a central opening and said punch being reciprocableinto and out of said opening, feeding means for advancing the webbetween said die and punch elements, said elements acting to cutsuccessive forms from said web, a chute beneath said die through whichthe out forms descend, a plunger reciprocable in said chute and throughthe opening in said die to tilt the out forms for passage through thechute and to raise the uncut portion of the web for continued movementbeyond the die and punch, and means for operating said die, said feedingmeans and said plunger in timed relation to one another, so that the topof the plunger is below the lowermost portion of the punch during thedescent of the punch and is raised upwardly to follow the punch to thelevel of the top of the die on the upstroke of the punch.
